A low-voltage cable branch box working condition online adjustment and alarm system

Abstract

An on-line adjustment and alarm system for working conditions of low-voltage cable branch boxes, comprising a working condition information collection module, a temperature / humidity regulating system, a working condition indicator, a front-end controller, a background server terminal, and an alarm management application software. When it is detected that the temperature / humidity index in the box has crossed the warning line, and after a period of continuous waiting, the detection data still exceeds the limit, then start the temperature / humidity adjustment system to adjust the temperature / humidity in the box, so that the branch box runs at the technical parameters Inside; since the temperature / humidity adjustment system starts, after a period of time, the temperature / humidity information collection unit and the front-end controller will detect the temperature / humidity in the box again and judge the working conditions. Actively send corresponding alarm signals to administrators and security patrols, and repeatedly prompt on the mobile phone APP module at a certain time interval, until the mobile phone APP module is manually queried, the prompt stops the alarm. The invention can effectively avoid the uncertainty and blindness of the maintenance plan and reduce the work intensity of the administrator.

Description

technical field [0001] The invention relates to the technical field of low-voltage cable branch box monitoring, in particular to an on-line adjustment and alarm system for working conditions of a low-voltage cable branch box. Background technique [0002] With the deepening of distribution network transformation, more and more overhead low-voltage lines have been transformed into buried cables. Therefore, the low-voltage cable branch box is widely installed outdoors in the distribution line, and it is a common branch box without any control switch or detection equipment. The incoming and outgoing lines of this type of branch box are physically connected together and have the same electrical potential, and are used for branching or branching wiring. Because the taps in the box are subject to unfavorable factors such as on-site manufacturing process and operating environment, the proportion of cable accidents caused by taps is as high as 90%. [0003] The monitoring of low-v...

Problems solved by technology

The ambient air temperature will have a great impact on the performance parameters of the branch box, sometimes resulting in excessive humidity in the box, resulting in condensation and serious corrosion of the wiring terminals; or due to overload and other factors, the temperature in the box is too high, and the heat in the sealed It is difficult to discharge in a timely manner in the box, and this state usually leaves many unfavorable hidden dangers such as a decrease in the insulation strength of the box
